Abstract

L'invention concerne une architecture de transcodeur et un procédé pour transcoder dans des systèmes radio mobiles terrestres (LMR). Le système LMR (20) comprend un premier site de communication configuré pour communiquer à l'aide d'un premier protocole de communication LMR et un second site de communication configuré pour communiquer à l'aide d'un second protocole de communication LMR. Le système LMR comprend en outre un transcodeur (28) configuré pour recevoir un contenu LMR du premier site de communication communiqué à l'aide du premier protocole de communication LMR et convertir numériquement le contenu LMR en le second protocole de communication LMR à communiquer au second site de communication.
